Why has the white working class abandoned the left?

Why did [Trump's] anti-government policies such as cutting taxes for the super-rich and slashing the newly established health care insurance system succeed to such a large extent? Moreover, why were these policies especially effective in securing votes from the white working class?

One answer may be in an issue often neglected by the left, namely how people perceive the quality of their government institutions. The idea behind this “quality of government” approach is that when people take a stand on what policies they are going to support, they do not only evaluate the policy as such.
